Alfred Wegener's proclamation of continental drift was initially considered a hypothesis because it lacked substantial empirical evidence to fully support it. A theory requires a well-established body of evidence and confirmed predictions, which were not present at the time of Wegener's proposal.
The man who pioneered the continental drift hypothesis was Alfred Wegener. He proposed the theory in 1912, suggesting that Earth's continents were once joined together in a single landmass called Pangea and have since drifted apart.
I think that continetal drift replaced his theory
Alfred Weqener's theory/ hypothesis was considered controversial because Alfred did not have an explanation for why the continents, North America, South America, Africa, Asia, Antarctica, Australia, and Europe have separated or moved.
A scientific theory is more elaborated than a simple hypothesis and generally is validated by experiments.

It helped us by creating the theory of seafloor spreading which is the proof alfred needed to complete his hypothesis

Did you mean Plate Tectonics Theory? - Plate Tectonics Theory is the combination of Continental Drift and Ocean/Sea Floor Spreading. BTW. The scientist who started it is Howard Baker continued by Alfred Wegener.
